Abstract: This disclosure describes systems and techniques for generating a disparity map having reduced over-smoothing. To achieve the reduction in over-smoothing that might otherwise occur, a third image is captured in addition to stereo reference and search images. Information from the third image, which may be of the same or different type as the stereo images (e.g., RGB, grey-scale, infra-red (IR)) and which may have the same or different resolution as the stereo images, can help better define the object edges.

Abstract: Techniques are described for generating a distance map (e.g., a map of disparity, depth or other distance values) for image elements (e.g., pixels) of an image capture device. The distance map is generated based on an initial distance map (obtained, e.g., using a block or code matching algorithm) and a segmentation map (obtained using a segmentation algorithm). In some instances, the resulting distance map can be less sparse than the initial distance map, can contain more accurate distance values, and can be sufficiently fast for real-time or near real-time applications. The resulting distance map can be converted, for example, to a color-coded distance map of a scene that is presented on a display device.
